ANDREWS STEININ GER, OF ALLEGHENY, PENNSYLVANIA.

FOLDlNG UMBRELLA.

To all whom itmay concern.-

Be it known that I, ANDREWS STEININGER, a subject of the Kingof Hungary, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented'oejiftain new and useful Improvements in "Fol Umbrellas, of which the followin'glis a fication, reference being had therein tofthe" accompanying'drawing.- L; 3' v This invention relates to'foldingurnbrellas, and its object is to .aprovide. an umbrella which may be readily folded into small compass and packed into a trunk or satchel.

The invention consists of sectional ribs of novel construction and improved means for connecting 'the same together and to the han- The construction of the improvement will befully described hereinafter in connection with the accompanying drawing which forms a part of this specification, and its novel fea- In the drawing, Figure 1 is a side elevation partly in vertical section of an umbrella frame embodying the invention, the folded position of the ribs being shown in dotted lines, Fig. 2 is a similar view showing the ribs in folded or closed position, Fig. 3 is a side elevation showing the outer sections of the ribs folded, Fig. 4 is a view in perspective Fig. 5 is a detail perspective of one of the connecting sleeves employed to connect the inner sections of the main ribs.

The handle rod or stick of the umbrella comprises two sections, designated respectively by the reference numerals 1 and 2. The lower section 1 to which the handle 3 is secured is tubular, and secured therein is an ordinary spring-catch 4. The catch 4 projects through a slot formed in 'the tubular section 1. The lower section 1 is also provided with the usual retaining catch 8.

Upon the upper handle rod section 2 is a notch 9 to which the inner ends of the main rib sections 10 are pivotally secured. Each of the main ribs comprises two sections '10 and 11, the inner section 10' preferably consisting of a single metallic strip bent centrally upon itself to provide a projecting perforated end 12, and two longitudinal sides 13 connected by a cross-pin 14:- Between the perforated outer ends 15 of each section 10 is pivoted a connecting sleeve 16, formed with Specification of Letters Patent.

and are endspf whic stretchersare connected to a g run-ner,20farranged'on the handle-rod.

-- :Th e rib sections 11 are further connected to the sections 10 by means of flat springs 21 secured at their outer ends to the sections 11, and at their inner ends to the pivotal su ports of the sleeves 1.6. To each of t e stretchers 19 is connected one end of a coil spring 22.. The opposite ends of these perforatedears-17. The outer sections 11 of,

the. main'iribs extend'through these: sleeves,

onne'cted by al'ink 1B withth'eg 1 he'l stretchers '1 9, the "inner springs are connected to the cross pins 14. of

the main rib sections 10, said springs resting in the spaces between the sides 13 of the said sections 10. These springs 22 act to automatically open the umbrella when the runner is released from catch 8.

The umbrella is shown in closed position in 'Fig. 2 of the drawings, Fig. 1 also showing in dotted lines the closed position of the ribs and stretchers, and Fig. 3 shows the ribs in the folded position. When the ribs and stretchers are in the closed position as shown in Fig. 2, and as seenin dotted lines in Fig. 1, and it is desired to raise the cover of the umbrella the spring catch which holds the runner 20 in lowered position on the umbrella stick is depressed, and, as the coiled springs 22 have been extended or expanded in the closing of the umbrella, the tension of these springs is exerted against the stretchers 19, and when the runner is released. as above noted, the springs cause the runner to be drawn upwardly on the umbrella stick, opening the umbrella automatically to a certain extent. Pressure against the runner suffi cient to force the same over the catch 4 is all that is required toeflect the complete opening of the umbrella. These springs 22 are placed under tension in the closing of the umbrella by reason of the fact that the links 18, when the umbrella. is in open form, lie substantially in line with the outer rib sections 11, whereas in the closed position of the ribs these links lie at substantially right angles to the outer rib sections, and the springs22 being connected to the outer ends of the stretchers, the distance between the outer ends of said stretchers and the pins 9 is greater when the umbrella is in closed position, than when the same is in the opened or extended position. When it is desired to With an inner rib section and an outer rib section, of a sleeve pivctally secured to the outer end of the inner rib section and through Which sleeve the inner end of the outer rib section is received, a spring secured to the outer rib section and pivotally secured at its inner end to said sleeve, a stretcher, a link pivotally connected to the outer end of said stretcher and the inner end of said outer rib section, a pin carried by the inner rib section near its inner end, and a spring connected to said pin at one end and at its other end connected to the outer end of the stretcher.

2. In a folding umbrella, the combination with an umbrella stick, a notch thereon, and a runner slidable on the stick, of ribs each formed of an inner and an outer section, the inner section pivotally secured at its inner end to the notch, a sleeve pivotally secured to the outer end of said inner section, the outer rib section having its inner end received through said sleeve, a spring secured to the outer rib section and pivotally secured at its inner end to said. sleeve, stretchers pivotally secured at their inner ends to the runner, links pivotally connected to the outerends of said stretchers and to the inner ends of the outer rib sections, and springs having one end connected to the outer ends of said stretchers and their other ends connected to the inner rib sections adjacent the pivoted inner end of the latter.

In testimony whereof I aflix my signature in the presence of two witnesses.
